As a Resident Evil Game... it definitely turned pretty bad plotwise and somehow the whole saga turned into a damn weird direction. S.T.A.R.S., the BSAA, Umbrella, Tricell, all these organizations involved with viruses, zombies and bugs and leeches and stuff. It's sad how Sheva never gets mentioned again. She was pretty damn cool, tbh.

But as a Coop-Game: This game is definitely a blast! Yeah, some puzzles were awkwardly designed, but the combat in Coop was damn fun and never boring. Planning strategies and resources together was really fun and there were some situations, that were damn intense.
I can't imagine how some boss fights or chapters work in a solo-game.
